This repository contains NASA's Platform Support Package (PSP), which is a framework component of the Core Flight System.
This is a collection of APIs abstracting platform specific functionality to be located in the psp subdirectory of a cFS Mission Tree. The Core Flight System is bundled at https://github.com/nasa/cFS, which includes build and execution instructions.
- Cleans up stale code from the previous methods of generating 1Hz. Adds a new PSP module that instantiates an OSAL abstract timebase for use with cFE services. This single module is used across all psp implementations (mcp750, pc-linux, pc-rtems). Results in 1Hz timing tick on MCP750 will be more accurate. No changes to Linux or RTEMS
- Fixes segfaults when
CFE_PSP_Portroutines are invoked on Linux. - Converts
cfe_psp_ram.candcfe_psp_port.cinto modular components and removes from the "shared" directory. The existing implementations become the corresponding "direct" module, and are enabled based on the psp module selection. Adds a "notimpl" variant where all the functions returnCFE_PSP_ERR_NOT_IMPLEMENTED. This is used on Linux or any other system where direct access is not possible. Renames the existingeeprom_stubmodule to beeeprom_notimplfor consistency and to avoid confusion with the unit test stubs. - Implements two PSP modules to provide
CFE_PSP_GetTimeandCFE_PSP_GetTimeBase, one for POSIX-compliant RTOS usingclock_gettime()and the other specifically for PowerPC processors on VxWorks that have thevxTimeBaseGet()routine. Clarifies and documents the difference and use cases forCFE_PSP_GetTimeandCFE_PSP_GetTimeBase. No impact to behavior. - Adds a coverage test for the VxWorks PSP timebase module and provides an example of how this can be implemented for other modules.
- See nasa#289 and nasa/cFS#238
- Removes unnecessary global config structure
Target_PspConfigDataand associated elements infavor of the new version API. - The mem pool stats TLM command now works on 64-bit Linux and sends out the expected telemetry packet.
Converts
CFE_PSP_MemoryTableto internal object (instead of external) that should only be accessed via the PSP API. Replaceuint32s withsize_t. Use full range (SIZE_MAX) in the Linux/RTEMS implementation. - See nasa#288 and nasa/cFS#233
- Includes
cfe_psp_version.cin the cmake source list, which was mistakenly omitted previously. - Applied the patch and confirmed that CS Cmake unit tests build. Unit tests relying on
CFE_PSP_GetKernelTextSegmentInfowill build. - See nasa#279
- Addresses the issue of incompatible/non-portable code blobs in the "shared" directory. It uses the same modular init pattern as is used elsewhere in cFE: CMake generates a list of "base" modules correlating with the selected PSP (i.e. pc-linux, mcp750-vxworks, etc) and these modules are then initialized (in order) before the rest of PSP runs. The "direct write" EEPROM is not used unconditionally. Instead the proper eeprom implementation module is selected based on which PSP is selected. MCP750 uses direct write, pc-linux uses an mmap file, and pc-rtems uses a stub (not implemented).
- Replaces " used on non-system header #includes with <>
- Adds a contributing guide that links to the main cFS contributing guide.

- HOTFIX 20210312, updates to work with older CMake
- See nasa#268
- Fix #246, remove unused code.
- Fix #254, use CMake to publish interface details
- Fix #256, add PSP version API
- Fix #258, Add Testing Tools to the Security Policy
- See nasa#260
- Updates continuous integration workfow by adding static analysis with timeout and code format check. Adds status badges to ReadMe and removes old TravisCI artifacts.
- Adds CodeQL analysis to continuous integration
- Apply standard formatting to psp codebase. Only changes whitespace.
- Adds missing "+dev" to development version output
- See nasa#250
- Add
Security.mdwith instructions on reporting vulnerabilities. - Rename
UT_ClearForceFailasUT_ClearDefaultValueto reflect nasa/osal#724 - Remove unused elements in
CFE_PSP_ModuleType_tenum to avoids irregular enum warning - See nasa#243
- Instead of accessing
OS_time_tmember values directly, use the OSAL-provided conversion and access methods. This provides independence and abstraction from the specificOS_time_tdefinition and allows OSAL to transition to a 64 bit value. - See nasa#240
- Add cppcheck GitHub Actions workflow file
- See nasa#234
- Updates the Readme for RTEMS and adds
README_RTEMS_5.txt. The changes include removing references to the CEXP module loader, and describing the development environment setup for RTEMS 5. - Remove obsolete OS_TaskRegister comment.
- See nasa#226
- Rename
UT_SetForceFailtoUT_SetDefaultReturnValuesince some functions that retain more than 1 value are not necessarily failing. - Use of the size_t type instead of uint32 in unit-tests to avoid a compiler type mismatch error on some platforms.
- See nasa#221
-
- Use event callback mechanism to invoke pthread_setname_np() such that the OS kernel is informed of the OSAL task name.
/procfilesystem on Linux now has actual task name, instead of all being core-cpu1. Thepthread_setname_npAPI requires_GNU_SOURCEto be defined when compiling - this can be local to PSP.
- Use event callback mechanism to invoke pthread_setname_np() such that the OS kernel is informed of the OSAL task name.
- Set REVISION to "99" to indicate development version
- See nasa#213
- Improves the module ID lookup when getting the CFE core text segment info. VxWorks PSP should use the real module name, not assume cfe-core.o when getting text segment info
- See nasa#209
- Use the osal_id_t typedef whenever dealing with an OSAL ID value.
- Resolves build error regarding redefinition of PPC macros in the coverage test, when building on the actual ppc/vxworks target.

- See nasa#184
- Restructure code to make more amicable for rebuilding in a unit test environment. No major changes, primarily just shifting code between locations/headers to support unit testing.
- Adds a char element
VersiontoCFE_PSP_VersionInfo_tcontaining the version number expressed as a string. Defines new macros for the Build Number and the Build Baseline. - See nasa#176
- Changes the PSP reference to be compatible with the change in nasa/osal#449 making the BSP modules more generic and changes the name.
- See nasa#175

- Replace 'OS_VolumeTable' with OS_FileSysAddFixedMap() in all PSPs.
- See nasa#166
- Removes non-termination string warnings when building with GCC9.
- Exception handling is now implemented on POSIX. There is no longer a separate handler for SIGINT - it is now treated as an exception and goes through the normal process which ends up "restarting" CFE. On pc-linux causes the process to exit normally. There is now a mechanism to capture the CTRL+C exception code and use it during normal test cycles.
